Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners causing excessive squeeze on the O-ring.Tighten fasteners to the manufacturer's specified torque values to avoid over-compression, which can lead to premature failure.
Using incompatible lubricants or cleaning agents that degrade the Buna-N material.Always verify lubricant and cleaning agent compatibility with Buna-N rubber before application. Consult material compatibility charts if unsure.

Common Applications

  • Hydraulic and pneumatic cylinder seals
  • Fuel and oil line fittings
  • General industrial pump and valve seals

⚠️ Engineering Warnings

  • Not recommended for use with strong acids, esters, ketones, or polar solvents.
  • Avoid exposure to ozone, UV radiation, and weathering for prolonged periods, as this can degrade the Buna-N material.
